Comodo Internet Security v10.0.2.6406 - RC

Hi All,
We are planning to make following version available via updates this week, with few fixes on top of last released version 6396.

In website filtering, newly imported lists disappears upon re-boot as reported here.

Right click scan is supposed to check AV updates before scanning files as “Manual Scan” option has related flag enabled in settings.

Installation over older version using web installer was failing in previous release.

In Windows 10 RS3, when alert asking action to be taken on unknown installer execution appeared, even if user opted to run with unlimited access, installer ran in Sandbox.

Online Setups:
In order to install online setups, please ensure you have following entries in Windows hosts (c:/windows/system32/drivers/etc/hosts) file:

As we would like to test update behavior, we would like you to either define hosts entries as suggested above or by adding as shown in enclosed snap.

You should also be able to update from v6294 to this version as well.

We would like you to update from previous versions to this version and share your feedback.
Unless we hear any blocker, this will be the version going live for updates this week.

Thank you very much for all the feedback in previous releases.


Hi Umesh,

Thanks for the release. Updated and everything looking good. :-TU

The usual freeze while upgrading though it could be just me.

:-TU :-TU :-TU

Just trying to install this but can’t. It tells me to uninstall the previous version (why? - just do it, please).
I have 2 Comodo Firewalls in Revo and I reckon that I uninstalled the wrong one. Now I can’t uninstall the FW and can’t install the new one.
As it happens, the FW is still fully functional, but I seem to be trapped!
Currently on

The imported lists in the Content Filter after the restart are not deleted

Updated and now running well. The only problem I came across was that for some reason, the update had unchecked the Trusted Network box, so Office, Acronis & everything web based didn’t like that, refusing to work, until I’d checked it again and restarted

Acronis True Image Monitor always seems to have a problem with a CIS upgrade, giving the error initially that it can’t start. It never happens on a clean install - just an update, but after a further reboot, they co-operate quite happily from then on

You should follow this guide to do a clean uninstall then re-install, you also should not be using revo to uninstall CIS/CFW.

Updating now. I had to move the IP address of the test server to the top to get CIS to see the update.

Thank you, futuretech.
I followed the instructions - a lot of rebooting and cleaning of the Registry and now I have a firewall again.
Thank you again.

Website Filtering does not apply these own created rules.
See attachment.
Comodo rules are disabled.
v6294 working well with these rules.


Try adding them without “/”
should work as expected

Every time I try to install CFW, I get a connection error.

I’m running the new Windows 10 Pro Fall Update

Did you change the hosts file as described in

Not having changed the hosts file entries may cause the 404 error.

Who is installed on the OS 10 1709, have problems?
I came to switch to OS 10 1703, there were problems.

@megaherz33 . Running 1709 without any problems from 1709.15 that came out with insiders.

No problem with the RC version?

Runs fine here on Win 10 Insider 170025.

CIS filters VPN?

Some VPN software yes, to check open vpn network adapter properties and see if Comodo firewall driver is listed and has checkbox enabled.

After rebooting or when reconnecting, all settings are reset.
